This invention relates to apparatus for and method of capping bottles.

Among the principal objects which the presentinvention has in view are:To provide animproved apparatus for capping bottles and the method of doing the same; to form the cap directly in place; to enable the cap to seal tightly within the neck of the bottle; to provide a cap completely formed on the bottle with a sunk portion within the bottle; to provide a tool for performing the cap forming and applying oporation; to obtain both the forming and the capping operation with successive movements on the part ofthe operator; to provide for using the tool with bottles of different height; and to obtain other advantages and results.

; as operated upon in Figure 2; Y

' and Figure 8 is an elevation oi. the completed cap;

Figure 9 is a sectional view shown as taken on line 9-9 of Figure "I. i

As seen in the drawings the cap forming and applying mechanism is shown generally as an up-- right standard Iii carried by a base II and having an adjustable table I! upon which to support the bottle or similar container I3 which is to be capped. At an upper part of the standard III is mounted an adjustable bracket it within which is carried a vertically slidable rack i5 operable by a lever l6 fast with respect to a pinion 11in mesh with the rack.

The cap forming and applying die is partly carried at the lower end of the rack it, above the table and movable toward the table as will readily be appreciated by those skilled in the art. For this purpose, there is shown a plate II at the bottom of rack It, said plate having near its peri-phery .a plurality of depending rods I! the lower ends 01 which are secured to and support a squeezing ring 20. The said ring includes within the same another portion of the die, the body II of which is rigidly carried by bracket 22 from 3 the standard III This body provides suitable curvilinear sockets 23 for receiving and retainpending through the ring and arranged side by side in a circular formation. Each finger is normally urged outward by a spring 25 between it and said body 2i.

The said body 2| is furthermore axially hollow at its lower part and provides therein a plunger head 26 which may conveniently have a sleeve 21 projecting upwardly therefrom into the axial ing the upper ends of fingers 24, said fingers deopening 28 of the said body portion for guiding said plunger head. The plunger head is urged normally to its lowermost position by a spring 29 within the sleeve, and downward movement is limited in suitable manner as by a headed stem 30.

The plunger head first engages-a disk blank 3| laid upon the top of the bottle and holds the same as the bottle is forced upwardly as by means of a lever 32 operating through a pinion 33 and rack 34 depending from the table through its supporting bracket 35. When the plunger head is seated as far upward within body 2| as it will go, continued raising of the table forces the lower end of said body with plunger head 26 into the neck of theobottle, carrying the subtended part of the disk into the bottle, thus providing the sunken portion 36 of the cap.

By properly shaping the lower peripheral edge of the said body 2!, the sunken portion or the cap may be caused to flt'tightly within the heel of the bottle. When this operation is completed, the upper lever I6 is swung down, thereby lowering the ring and squeezing fingers 24 inwardly, thus capping the bottle while the forming portion of v the dieis still within the sunken portion of the cap. A tight seal is therefore maintained between the sunken portion and the bottle while the edge of the cap is formed around the upper edge of the bead of the bottle.

I claim:

1. An apparatus as characterized comprising a standard having a base. a slidable table adjacent 'said base {or holdix g a bottle, said bottle having .comprising a bracket extending from the standard and in parallel relationship to the said first bracket, said bracket having a rack and pinion therein and a hand lever for operating the same, said rack having at its lower end and secured thereto a circular plate, said plate adjacent its periphery having a plurality of depending rods for exerting a downward pressure, said rods secured to and supporting a ring, and said ring having therein a die providing means for shaping the cap to the bottle when the said lever lowers supporting bracket, said means comprising a rack depending downwardly from said table, a pinion mounted in the bracket and juxtaposed to said rack, a hand lever for operating the pinion and rackwhen raising the table and bottle, means mounted on the standard towards the top thereof for pressing the cap into the neck of the bottle as the table and bottle are fully raised, said means comprising a bracket extending from the standard and in parallel relationship to the said first bracket, said bracket having a rack and pinion therein and a hand lever for operating the same, said rack having at its lower end and secured thereto a circular plate, said plate adjacent its periphery having a plurality of depending rods for exerting a downward pressure, said rods securedto and supporting a ring, and said ring having therein a die providing means for shaping the cap to the bottle when the said lever lowers the said plate, rod and the ring whereby when lowered will engage the outer edge of the cap and seal the same to the upper outer edge of the neck portion of said bottle, and said die means comprising a bracket extending from the standard and parallel to the said other brackets, the said bracket rigidly supporting a body member, said body member being stationary and having a plurality of curvilinear sockets, a plurality of fingers depending downwardly therefrom and adapted to be retained in place by the ring whereby when the ring is lowered the said fingers at their lower ends will clamp the outer peripheral edge of the cap against underside of the outer edge of the said neck portion of the bottle.
